We just got the new flash-based attachment uploader working. Feel free to test it in this thread by uploading attachments. To delete attachments once you're done, simply click "Settings" in the top right, scroll down to "Attachments" in the list on the left, then delete the ones you don't want. Another nice feature is the ability to change the image settings once it's attached in the thread. Put your cursor over the photo until you see the pencil, then click. It'll pull up a box with some options in there such as image size which you can select to change the way it displays in the thread. As always, to enlarge attached photos simply click the photo.
